is experienced in keeping the rails seated on mounted the base of therail in a chair hav- Be it known that I, BEVERLY J. Gnmrns, of SouthFramingham, county of Middlesex, State ofMassachusetts, have invented anInnprovement in Chairs to Hold Railway-Rails, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters and figures on the drawings representinglike parts.

In laying tracks for railways great d ifliculty and the loosened spikesare liable to be re moved and the sleeper is worn. To obviate thetendency of the rails to spread, I have ing walls or projections tocontact with the opposite edges of. the base, and this chair isprovidcd'with a pocket, in which may be placed a locking device toengage a suitable notch or projection of the spike when the sameis'driven through said chair, so that its l a chair has ever beenprovided with a shoulhead overlaps said flange. i

Figure 1, in perspective, shows two rails abutted in one ofmy improvedchairs and a.

fish-plate applied to the rails, a portion of the chair being broken outto showthe locking device; and Fig. 2 shows a rail in-achair, oneof thepockets being broken out.

Let A A represent rails of usual construction, each having a flangedbase a. The fishplates B may be applied to the junction of two rails bysuitable bolts 1) in usual manner.

My invention relates more especially to the chair 0. It is composed of ametallic plate havingsuitable shoulders c to constitute ab utmen'ts torestrain any sidewise movement of a the rail under pressure of a carrunning onable stud e c, said spring being contained in said pocket andkept therein by a pin or stud e".

In Fig. 2 the device e is made as a'single spring held in place in thepocket by a suit- When a spike is :being driven through the chair intothe sleeperor tie, the

.wedge part2 of the projection 01 acts against the end of the lockingdevice and forces said end back, and when the spike has been 'fullydriven the spring part of the locking device acts to cause the freeendof I the locking device to enter the space (1 and hold the spike lockedin its driven position. To withdraw a spike, a wedge maybe driven intothe. open end of the pocket and, acting against one side of the lockingdevice near its end, said looking device may be forced back to free thespike and let it be lifted by any usual driver or tool.

When a fish-plate is needed, it may be pro: vided near its lower endwith a downturncd lip a, which may be interposed between the edge'of thebase of the rail and the shoulder a.

I am not aware prior to my invention that der or shoulders to contactwith the 'base of the flange andoutside said shoulder or shoulders witha pocket to receive a locking device, a spike being extended throughsaid pocket and chair, and hence this invention -Having described myinvention, what I claim as new, and desire to secure by Letters Patent,is-' 1. A rail-supporting chair adapted to rest on and cross a tietransversely, said chair presenting parallel projections to receivebetween them the edges of the base of the rail, and a longitudinalpocket at the edge of the rail, said pocket having a transversespikehole and receiving a locking device to cooperate with and lock inposition aspike driven through said pocket of said chair into a tie,substantially as described.

2'. A chair composed of a bottom plate, having a pocket at eachlongitudinal edge, said pocket being provided .with a transversespike-hole, a movable locking device ins-aid pocket and crossing saidspike-hole and adapted toenter a notch in one edge of the spike,substantially as described.

3. A chair having a pocket provided with a transverse spike-hole, alocking device pivoted in said pocket and crossing said spike hole, anda spike having a' notch at one edge to be engaged by said lockingdevice, substantially as described.

4. A chair having a pocket provided with a transverse spike-hole, alocking device in said pocket and crossing said spike-hole, a spikehaving a camshaped projection and a notch, said projection actingagainst said locking device to spring it back so that it may thereafterreturn and enter said notch, substantially as described.

5. A chair to support meeting ends of rails, said chair having ashoulder, a fish-plate bolted to saidrails and havinga lip extended intothe space between the shoulder of the chair and'the edge of the base ofthe rail, and a spike driven through said chair and overlapping thefish-plate, substantially. as

described.

6. A chair for railway-rails, it presenting parallel shoulders to holdthe edges of the base parts of therails in position against lateraldisplacement, pockets extended parallel with said shoulders and havingspikeholes, suitable locking devices located in said pockets, andfish-plates united to the ends of rails and'extended toward saidspike-holes,

combined with spikes driven into said spike- 1 holesand overlappingparts of said fishplates, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence'of
